You are right in my opinion, I did not like Hegners under table dust collection. Right now I have the best set up I have ever had. And I get the most dust collected. But to do it I had to go to a smaller cigar box. The funnel setup took half the room of the older box. I tried without a box but I missed it so much I had to drag out a littler one. But I still have a Lot of air noise. So much so I wear hearing protection. I am running out of cigar boxes. I had such a nice collection. No, I rarely smoke a cigar, but I got into building cigar box guitars and kinda got carried away collecting the boxes. If you want a fun hobby get into cigar box guitars and Ukes. It is really fun, even if you don't play. I still have the first one I made, didn't use a cigarbox, didn't have one so I made the box also. I also have the last one I made which is a Uke. Last time my son was home he tuned my uke for me, and he said he wished I would go back to making them.. He plays guitar and loved to mess around with my CBG's. Just another great hobby.
